SR 520 Eastside project overview

Crews working on the Eastside Transit and HOV Project are widening SR 520 to six lanes between Medina and Bellevue, rebuilding interchanges, constructing highway lids and median bus stops and installing fish-friendly culverts. In 2010, WSDOT awarded a $306 million design-build contract to Eastside Corridor Constructors, a joint venture of Granite Construction Company and PCL Construction Services. The completed Medina-to-Bellevue corridor is targeted to open to traffic in December 2013.
